As a conclusion, when executing stored procedures that only return update counts output parameters will be available immediately, as jTDS will process and cache the whole response.

The only major jtes missing from jTDS are connection pooling and row sets; the reason for leaving these out is that there are free implementations available, probably much better than anything we could come up with. Of course, we will keep offering support on our SourceForge forums just as we did until now.

This means among other things that it cannot access platform-specific features, such as determining the currently logged user and his credentials. These benchmarks are free to download so we encourage you to do it and run them yourself.
